Motor hall sensor circular and simple introduce _ ndfeb strong magnet manufacturers
Brushless motors and some constant speed motor hall sensor magnetic ring, often need to used in brushless motor industry or call hall sensing magnetic pole, because of hall sensor magnetic ring are generally multipole magnetic ring, its working principle is to rely on the circular multiple poles and induction hall element, in order to test the speed and efficiency of the motor, and can according to the hall sensor magnetic ring for the signal to control the motor operation work.
Constant speed motor and pump some special hall sensing multipole magnetic ring, mostly ferrite homosexual magnetic ring, the stable magnetic ferrite beads, magnetic pole, provides a stable pole original hall sensor signal, which application is widespread in terms of speed.
Below brushless dc motor magnetic ring (magnetic encoder
Hall sensor circular and generally do not need too strong magnetic, as long as they have multiple poles are arranged and provides hall element with the magnetic signal, the normal work of the hall element can get signal.
So, hall sensor magnetic ring for more gay ferrite beads, the stable magnetic ferrite beads, magnetic pole, provides a stable pole original hall sensor signal, which application is widespread in terms of speed.
And according to the requirement of the brushless motor with different axial multi-polar magnetic ring and radial multi-polar magnetic ring, magnetic ring, magnetic table generally around 1000 gs, magnetic too strong or weak, so just can give original hall sensor signal, and will not affect the normal work of the motor itself, the circular.
However, because of different industries, the product of the professional term is different also, have a hall sensor magnetic ring, induction magnetic multipole induction magnetic ring, hall, radial induction radial multi-polar magnetic ring, magnetic ring, and so on, but after understanding of product usage, is for the most part can be determined by inductive circular hall, gay radial multi-polar hall induction copper prices low, magnetic stability in brushless motor, stepping gear motor, etc. Products are widely used on.
Induction motor hall magnetic ring was mostly with ferroferric oxide iron powder with trace rare earth elements of sintering permanent magnets.
Hall sensor ferrite beads are divided into axial multi-polar magnetic ring and radial multi-polar magnetic ring, magnetic method is mainly based on customer requirements for processing production, tongfang sexual permanent magnetic ferrite magnet has a special advantage in magnetization, magnetic orientation can be set according to the magnetizing fixture and optional magnetization.
